'The containers are now supported for free rotation about their'own axes.

associated with the coating rolls During continued rotation of the turretgthe chucks, vthe containers, and the brackets I84, I85 move radially inwardly andvfollow the intersecting arc of the coating roll periphery. As the containers leave the coating roll; of course, these elements a all move outwardly again to the initial position. When the chucks reach the position represented at 2H in Figure 12, thecamfollowing rollers I91 encounter a rise: in ;the cam' I96, whereupon the can-engaging chuck elements are withdrawn and the cansare deposited by gravity upon appropriate supporting brackets 33 associated with the out-feed conveyor 34.

As a result of theadjustments heretofore described, the thicknessof the layer of coatchucks and the means for actuating the same,

orlany equivalent construction, may be substiv Operation 7 I In the operation offthe embodiment of the invention described above, the containersare' received by pockets I86, I81 in the turret; as the turret rotates past 'thesinfeed chute .3I'.;-. ,The cam I96 at this point has withdrawn the chuck elements I90, I9 I so that the containers may drop into the pockets. When reachingvthe position indicated at 2) in Figure 12, the cam following rollers I91 drop into a 'depression on-the face of ,the cam (Fig, 15) thereby permitting the ing material may be accurately controlled.-

It will be evident from a consideration of the relative size and position ofithepulleys, gears and sprockets in Figure 1, that the coating roll 32 ro-' tates far more rapidly thanthe turret and in the, same direction (counterclockwise m Figure 1)..

Thus, as the containers approach thecoating roll by downward'movement 'onthe turret, the adJa-I cent face of the roll is moving upwardly at'high speed; When the vcontainers and the "chuck spindles contact the rolland the driving discs I21,- I28,- the containers and chucks aredriven'primarily bythe driving engagement between the discs and chucks, with theresult' that the 'con- Ii tainer's'make rolling contact with the coating roll 1 during their movement along the intersectingarc of the surface of the roll,.which movement is permitted by the radial-inwardmovement of the? The movement tothe. containers in rolling contact with the coating roll, thechuck elements I00, ISI and the driving discs I21, I28 limit the pressure applied between the surfaces of the containers and the coating roll! Th springs 200 which urge the chucks radially outwardly would apply a varying pressure between'thecontainers and the coat! ing rolls, were it not for the fact that the movement of 'the containers inwardly toward the 0 center of the coating roll isdefinitely limited by the metal to metal contact between theperipheriies of the chuck elements 1-90, m and the discs I21, I20. Hence, the containers mak onlyfla'desired, predetermined coating contact with the rubber surface of the coating-roll. -e 1 The number of rotations madeby. the containers while in engagement with the ,c-oating roll may bevaried by adjusting the position Qf the coating assembly relative to the can-holding tur= \ret, since'this adjustment varies the length ofthe maintaining a. layer 6f oztin wave the ent n s n hei v men w he. r etmpvi a he coat a s m y inflars n td the center of the turret, the containers move-I radially inwardly 0f .the tiirrej'. an; increaseqdist n ean xfc l w 1a onwnarc on; @h w the co tm r011, vw e. iiih o in ass m l cv'i de e d .Thslle th f ,the i e ti arc, d mm o r t tio al s e en h c ti roll and thwu ret'i mth', si fi m n thfi num e o o at on nwinv vby th w ai 's h m in contact h the oat ngrq h, S e. t 1 p ed. fi
